Title: Chopped current controller for electric motor
Inventor: TATSUMI TERUO
IPC: H02P29/00
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To make time until the temperature of the first and second switching elements reaches the allowable temperature limit longer than conventional. SOLUTION: Generally, chopped excitation is conducted in a switching mode which retains the ON of the second switching element 6, and repeats alternately the ON and OFF of the first switching element 5. The loss in the switching element 5, 6 caused by conducting chopping in this switching mode is larger in the second switching element than in the first switching element, so that the temperature in the switching element 6 becomes higher than that of the switching element 5. When the temperature in the switching element 6 reaches a prescribed temperature set lower than an allowable temperature limit, the switching mode is switched to a switching mode which keeps the first switching element 5 ON, and alternately-repeats ON and OFF of the second switching element 6, thus reducing the heating in the switching element 6.

Abstract: PURPOSE:To shorten the processing time of a timer control system by providing plural timer blocks which are used for each timer request, a timer queue register table having the register number A, a counter which overflows with the value A, a timer register means, and a time-out detecting means. CONSTITUTION:One of timer blocks 81-87 is secured at timer register request for the acquisition of the value obtained by adding the counted value to the requested timer value. This obtained value is divided by the register number A of a timer queue register table 7 and the timer blocks secured previously are queued in the time-out order to the timer queue of the register table which is retrieved by the quotient remaining value. Then the value obtained by subtracting the sum total of the values set at the timer blocks queued before a relevant timer block from the quotient value of the value A are set at the timer block and then registered into a timer. Then '1' is subtracted from the value set previously as long as this value is not equal to 0 and the operation is through. While a time-out state is decided when the value set previously is equal to 0 and the same process is repeated to the head timer block for detection of the time-out state. In such a way, the processing time is shortened in a timer control system.
